[Asterisk-Users] HELP: agi-test.agi does not return any DTMF!

[vasya at azhelp.net]

Hi all,

Tiny, but very important question for me: what it can be when standard
agi-test.agi script, like:

print STDERR "Testing 'waitdtmf'...";
print "WAIT FOR DIGIT 10000\n";
my $result = <STDIN>;
&checkresult($result);

on the call from KPhone application does NOT return any DTMF code back (I use
dtmfmode=inband in sip.conf):

Testing 'waitdtmf'...PASS (0)

Does anyone could give me a little help?
Thanks.

Vasya
